How to insert array into mysql using PDO and bindParam?
- by moomoochoo
I'm using the following code. The code works, but I want to change it so that it uses bindparam
try {
$dbh = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password);
$stqid=array();
for ($i=0; $i<$array_count; $i++){
$stqid[$i][0]=$lastInsertValue;
$stqid[$i][1]=$qid[$i][0];
$stqid[$i][2]=$qid[$i][1];
}
$values = array();
foreach ($stqid as $rowValues) {
foreach ($rowValues as $key => $rowValue) {
$rowValues[$key] = $rowValues[$key];
}
$values[] = "(" . implode(', ', $rowValues) . ")";
}
$count = $dbh->exec("INSERT INTO qresults(instance, qid, result) VALUES ".implode (', ', $values));
$dbh = null;
}
catch(PDOException $e){
echo $e->getMessage();
}
I replaced the following
$count = $dbh->exec("INSERT INTO qresults(instance, qid, result) VALUES ".implode (', ', $values));
with
$sql = "INSERT INTO qresults (instance, qid, result) VALUES (:an_array)";
$stmt = $dbh->prepare($sql);
$stmt->bindParam(':an_array', implode(',', $values),PDO::PARAM_STR);
$stmt->execute();
but the insert doesn't work anymore (I didn't get any error messages though).
QUESTION: What am I doing wrong? How can I rewrite the code to use bindParam?
